Rug,
You can get the appropriate headspace guages to figure out if it’s too deep.
If it is - Blueberry or EABCO barrel works could fix it for you.. by shaving some off the face of the barrel and moving the lug forward a few thousands... but first I’d do the gauge testing to see how far forward it is.
** remember 10 thousands is the max headspace you’d want, so you are probably a bit longer than you might want it but not to 10 if someone just ran a AI reamer in the standard chamber ... that is unless they moved the neck shoulder junction forward much.. Frankly when cutting a chamber you almost can’t feel a thousands or so unless you know what you are looking for and what you are doing, it’s the slightest of cuts.
OR
You can just not shoot standard brass in it and deal with the slightly longer head space by by neck sizing, and only bumping the shoulder...
